My friends and I had a great time at Vittaya's place. The house is about 5 to 10 minutes' walk to the nearest BTS station, which is just a few stops away from the main Sukhumvit shopping district. The neighbourhood is quiet and have lots of dining options if you choose not to go into the city.
The five bedrooms in the house were spacious, and the beds were very spacious. There is a kitchen where you can cook if you like, incluidng a coffee machine.
The host was very responsive and answered our quesitons promptly. he also helped to arrange pick up service from the airport to his house.
Overall, I would highly recommend this place if you are going to Bangkok for your next holiday.
